The comments from Jerry Thrasher and Jon Rosdahl on aj PAR
Jerry suggested removing the references to 3 specific documents in Section 5.2 (Scope of Proposed Standard) and he further mentioned that two of these references did not seem to be readily available.
Jon suggested revising it as “… also defines the modification to the PHY and MAC Layers to enable the operations for the GHz frequency band (pending approval from China MIIT of PRC) that comply with the applicable MIIT of PRC rules reference document”.

The response to comments from Jerry Thrasher and Jon Rosdahl on aj PAR
Agree with Jon and Jerry’s comments
The changes are as follows
Moved “The GHz frequency band is pending approval from China Ministry of Industry and Information Technology (MIIT) of People’s Republic of China (PRC)) that comply with the applicable MIIT of PRC rules reference document (MIIT XWH , MIIT XBW , cmmw.” to Section 8.1 (Additional Explanatory Notes) with some modifications due to other comments

From Shellhammer, Steve
TITLE: Please consider changing title to “…Enhancements for Very High Throughput to support Chinese millimeter wave frequency bands.”
SCOPE: Change “The amendment shall maintain the backward compatibility…” to “The amendment shall maintain backward compatibility...”
PURPOSE:  Change “pending for approval” to “pending approval”
GENERAL:  The PAR needs editing for grammar.

The comments from Png Khiam Boon on aj PAR
With regards to the PAR for aj PAR submission (DCN: IEEE /0140r5), in the title of the standards field, it is stated “....to support one or more of the Chinese GHz and GHz frequency bands”. However, throughout the rest of the document, especially in the scope of the project fields, “ GHz frequency band” is used instead of the less restrictive description of GHz. I feel that, at the very least, consistency throughout the document should be maintained and one of the two frequency ranges should be chosen. Moreover, it would be more prudent to include the less restrictive description of GHz.

The response to comment from Png Khiam Boon on aj PAR
In response to a comment from , the title was changed to “…Enhancements for Very High Throughput to support Chinese millimeter wave frequency bands.”. This eliminates the mismatch between the frequency band previously specified in the title and the rest of the PAR
To be less restrictive, “ ” was changed to 45.

The comment from James Gilb on aj 5C
The 5C question for compatibility changed following the March meeting.
Did you use the most recent version of the OM when you prepared your 5C?
It is item 2 in the 5C, subclause
